Guarding against reprisals in the wake of Osama bin Laden’s death, Chicago0area security personnel stepped up their vigilance Monday at high-profile spots: the Daley Center, religious centers and the United Center, among others.

On foot, by camera, by car, the surveillance reflected a renewed norm in the post-bin Laden world: keeping careful watch on possible targets, without knowing whom the attackers might be or even if they will strike.

Although many security measures remained behind the scenes, basketball fans discovered one immediate change: new metal detectors at the United Center for Chicago Bulls playoff games and at all NBA playoff games nationwide.
